What is a caribous niche?

The caribou's niche encompasses its role as a herbivorous herbivore in Arctic and subarctic ecosystems. It primarily feeds on lichens, grasses, and shrubs, contributing to the dynamics of plant communities. Caribou also serve as a prey species for predators like wolves and bears, thus playing a critical role in the food web. Additionally, their migratory patterns help in nutrient cycling and landscape regeneration.
